Free Flow plate heat exchangers

Free Flow plate heat exchangers

Our SONDEX® Free Flow plate heat exchangers are excellent choices for applications that use media with particle-rich contents, fouling tendency, or high viscosity. We customize each Free Flow heat exchanger to suit your application and media type. The contact-free plate channels ensure an unimpeded flow and long intervals between cleaning.

We set the new standard for improved performance and reliability when your media require gentle treatment and are unsuitable for regular heat exchangers due to viscosity, fouling tendency, or particle contents.
